Embodiment Construction

[0029] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments, however, can be embodied in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted. Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0030] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, such as according to the direction of the example descri...

Abstract

The invention relates to the technical field of integrated circuits, and discloses an oscillation circuit which comprises an oscillation module which comprises an odd number of cascaded first phase inverters, and the output end of each stage of first phase inverter is connected with the input end of the next stage of first phase inverter, the output end of the last-stage first phase inverter is connected with the input end of the first-stage first phase inverter; the power supply module is connected with the oscillation module and is used for providing working voltage for the first-stage first phase inverter; and the voltage adjusting module is connected to the joint of the oscillation module and the power supply module and is used for accelerating the establishment time of the node voltage at the joint. The voltage regulation module and the power supply module can provide corresponding power supply signals for the first-stage first phase inverter at the same time, so that the first-stage first phase inverter can obtain the power supply signals provided by the power supply module and the voltage regulation module at the same time, and the establishment time of the node voltage at the joint can be shortened; and the starting speed of the oscillating circuit is accelerated.

Description

technical field [0001] The present disclosure relates to the field of integrated circuits, and in particular, to an oscillator circuit. Background technique [0002] Oscillators are an important part of electronic systems and have played a very important role in the fields of communication, machinery, electronics, and navigation since their inception. Voltage Controlled Oscillator (VCO, Voltage Controlled Oscillator) is an adjustable signal source whose oscillation frequency can change with the applied control voltage. It is widely used in modern communication systems, especially in phase-locked loop, clock recovery and frequency In integrated circuits, VCO has become a key component that affects the performance of the entire system. [0003] However, in the related art, when the oscillator starts up, there is a problem of slow startup, so the oscillator needs to have a faster response speed. [0004] It should be noted that the information disclosed in the above Backgroun...
